6 FAQs about [Ceramic capacitor half-year work summary]

Are ceramic-based dielectric capacitors suitable for energy storage applications?

Can ceramic capacitors be used at 150 °C?

Ceramic capacitors are frequently deployed in intricate environments that necessitate both a broad operating temperature range and excellent high-temperature energy storage performance. Therefore, the P - E loops of BT-SMT-0.2NBT RRP ceramic were collected at 150 °C in this study (Figure 2a).

Are capacitor materials a good choice for high-temperature and power electronics?

Currently, research on capacitor materials for high-temperature and power electronics focuses on achieving new record-breaking limits for dielectric properties or energy storage densities, with little regard for the stability of key parameters during operation or component reliability.

Do nano-segregations increase the breakdown strength of multilayer ceramic capacitors?

Simultaneously, the nano-segregations around the grains can enhance the breakdown strength obviously due to strongly scattering of electron carriers and impeding of elec-trical breakdown pathways. Furthermore, the multilayer ceramic capacitors (MLCCs) using such dielectrics were constructed with en-ergy density of 16.6 J cm 3 and efficiency of 83%.
